Minecraft is a game about breaking and placing blocks. At first, people built structures to protect against nocturnal monsters, but as the game grew players worked together to create wonderful, imaginative things....Written by Hand_of_Doom244.22K

I have the same problem as distroyer117 - the game starts after selecting "play", there's a window called Minecraft 1.6.1, Mojang screen and crash without any error pop-up. I've just updated my java. (Windows 7)

Alright, I have got it downloaded and installed without issue. There is no virus, it is common for a torrented game and/or crack for a game to be mistaken for a virus. I have a top rated paid for antivirus program and I have never had any problems with the many games I have torrented.
Now this torrent is not perfect, as the uploader as mentioned version 1.6.1 does have a bug when trying to play on Windows 7. And like the others who have said they have had problems with that, I do as well. But I do have it running 1.5.2 perfectly fine. I am sure that the bug will be fixed in time, you can not expect for a torrented item to always be perfect and work just like if you had bought it.
Lastly, for all those who wonder if this has a place for texture packs, saves, or mods that you can add things to; it does.

Does this use a cracked/modded version of the new Minecraft launcher to bypass authentication, or still an older launcher variant?
Also, Minecraft 1.6.2 was just recently released. I happen to alrwady own a legit copy of the game, but just for the heads up. :)
